Ah, the distinct aroma of Fido's finest, now lovingly infused into your beautiful leather sofa. A scent that says 'home,' but perhaps a little too loudly. While the provided internet search results offered some dramatic tales of dog vomit and couches of questionable material, let's stick to the classic, lingering "eau de dog" issue on genuine leather.
First, you must evict the furry squatters and their dander accomplices. Grab your vacuum and its soft brush attachment. Go on a deep-seated archeological dig for every last dog hair and crumb of contraband kibble hiding in the crevices. You can't defeat an enemy you can't see, and lingering dander is a primary source of the funk.
Next, we concoct a magic, yet simple, potion. Mix equal parts water and white vinegar in a bowl. Before you go dousing your prize possession, please do a spot test on an inconspicuous area, like the back or underside. We're trying to de-stink the couch, not give it a weird new abstract art stain. Once you've confirmed it's safe, dampen a soft microfiber cloth with the solution—think damp, not sopping wet, as leather is not a fan of swimming—and gently wipe down the entire surface of the sofa. The vinegar works to neutralize the odor-causing bacteria.
Allow the sofa to air dry completely. The vinegar smell will be a bit assertive at first, but it will dissipate as it dries, hopefully taking the dog smell with it into the great beyond. If a stubborn scent remains, you can place an open box or bowl of baking soda near the couch (not directly on the leather) to absorb lingering odors from the air.
Finally, once your sofa is dry and deodorized, it's time for a spa day. All that cleaning can be very drying, darling. Apply a high-quality leather conditioner according to the product's directions. This will restore moisture, keep the leather supple, and create a protective barrier against future olfactory assaults.
